   What is a dummy variable in regression analysis?

   • A dummy variable is 0/1 valued binary variable. In regression analysis, dummies can be used to represent a boolean variable, a categorical variable, a treatment effect, a data discontinuity, or to deseasonalize data.

   What is a regression coefficient on a dummy variable?

   • In general, the regression coefficient on a dummy variable gives us the average increase in observed when the dummy is equal to 1 (with respect to the base case in which the dummy is equal to 0). Let us continue with the previous example, to see how a dummy variable looks like when the data is gathered in a matrix or table.

   How many dummy variables can a regression test take?

   • Their range of values is small; they can take on only two quantitative values. As a practical matter, regression results are easiest to interpret when dummy variables are limited to two specific values, 1 or 0. Typically, 1 represents the presence of a qualitative attribute, and 0 represents the absence.
